Default Re: HELP! Need to boost volume of .cda or .mp3 file!!

Quote:
The .cda was the type of file that my computer says is on that CD. It did not say it was a .wav file.
This is correct. This is how any audio cd works. Highlight all the .cda files (in Windows), right click, and select properties. They'll end up being very tiny. Obviously, there are much bigger files hiding their somewhere. I'm not sure why, but this is how audio cds work. You have to rip the MUCH large files to get access to the .wav files.

Trust me. This is 101 level stuff. I've been doing this for 6 years.

The sound system it was recorded on was at a local church. I have no idea what the system actually is.
Was it a computer or something else?

That remains to be scene. I can't see you at all! har har

I wound up using WavePad (NCH Swift Sound) to do some tinkering.
I've never heard of it. That doesn't mean it isn't good, but it's not typically used in big boy recording studios or whatever.

Then, I highlighted the entire song and "normalized" to 25% (is that what you meant by compressing?).
No. Normalizing and compressing are not the same things although will both get the volume louder. There is "peak" normalization which finds the loudest part in a song, figures out how far from the peak this bit of sound is and boosts the entire track that amount. RMS normalization is a little trickier and will do all kinds of weird things to your track.

A compressor will knock the top off the peaks and then allow you to push the overall volume up. This is pretty straightforward in Audacity, if memory serves me.

I must say that I'm confused by this whole % thing.

Every audio software program I've ever used used dB (decibels). The % is probably very confusing because dB is a logarithmic measurement. % is linear, I guess.
